- XCSme 6y agoA privacy issue example if a shared cache is implemented: jQuery v2 is installed and shared between sites A,B,C. If user goes to site B for the first time and the file is in cache (never requested from it), then it means the user has also visited A or C. If more files like this are shared, then, based on the requested files you can somewhat estimate which websites a user visited before.
